SAMCO - E46 Silicone Coolant Hose Kits (Non-M)

Unlike knock offs, SAMCO hoses are made from the finest European
silicones specifically designed for automotive use, and their light
blue SamTek® lining used on all hose interiors has delivered
outstanding resistance in the harshest environments over the last
12 years experience.
This is the quality you can trust, from the leader in motorsport
grade hose kits.

Now available for the Non-M model E46. The 323, 325, 328 and 330
can all run even hotter than the M3 as they have not the coolant
system design specifically for high performance use. While the OE
system is robust, drivers who own supercharged cars, or who do high
performance driving always want to ensure no cooling system issues
arise; especially considering the expensive and easy to damage
aluminum motor present in most E46s.
